fTo `all 'whom it may concern .1

Be it known that I, HENRY HERMAN, a citizen of the United' States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented new `and useful Improvements in A paratus for Ap plying Hinge-Pintles to ox-Part Blanks, of which the following is a specification.

This inventionrelates to apparatus for applying hinge pintles to box part blanks, and has-particular relation to apparatus for producing the pintle-receiving configura-v tions of the blank and applying the pintle to such `configurations by a sequence of automatic o erations.

Metal ic boxes of the hinged type generally employ a pintle structure on one of the box parts. In order to provide for approximate uniformity of product andlow cost of manufacture, it is desirable that the pintle application be produced automatically. Attempts have been made to produce this result in various ways, a satisfactory solution of the problems involved bein that disclosed in the patent, to Alexander George, No. 1,117,030, irl-which .thepintle has one end introduced beneath "an ear of thebox part a distance greater than that -rel uircd in the completed product, after whic fthe other end is positioned in alinement with Athe entrance to its ear and the pintle moved backward so as to insert the latter end. This general method enables the pintle to be inserted in an eiicient manner, and is employed in the present apparatus.

To provide for pintle applying by this method, it is essential that the box part to which the pintle is to be applied, have its configuration produced on to its being placed in posiapplying, it being under stood', of course, that the ears beneath which the intle is to be secured must be present in tlie box part before the pintle can be initially inserted. The treatment of the box the blank prior tion for pintle part blank to produce this configuration has generally been provided in separate apparatus, the two types of apparatus being entirely independent.

Each of these operations-the initial inanipulation for preparing the blank and subsequent pintle applicationpractically repart be positioned ou a supporting form at the time when the operation takes place, this form conforming more or less to the configuration of the interior of the Walls of the box part, these operations taking place on one of these walls. In other words, the form is of the male type with respect to the box part blank. Consequently; in each of these operations, it is necessary that the box part be first placed in position on the form, then operated upon to produce the desired result, and then removed rom the form. Obviously, this involves a more or less accurate positioning of the box part, and, so far as I am aware, this positioning and removal has heretofore been provided manually. As a result, the` capacityo the apparatus is more or less limited by the ability of the operator to provide the positioning'and removal operations, and the uniformity of product is also more or less dpendent upon the careful attention of the operator in positioning` the box part blank. Consequently the success of the general operation is more or less dependent on the manual dexterity of the operator; attempts at high speed tend to increase the number of defective structures, it being readily understood that not only is substantial accuracy mation of the ears in Y may be properly inserted, but the completed structure must be substantially accurate in order that the complementa] box pa1t--also generally made by die structures- Will not only assemble with the pintle carrying part, but will` when assembled, provide forr'a proper mating relation with the Walls of the box part in closing.

he present apparatus is designed not only to produce the pintlereceiving configuration and apply the pintle in the same machine, butto provide these operations automaticallyand in an automatic sequence through the use of a feed mechanism vvhich will providethe successive positionings and removals in proper manner and in timed sequence, meeting the various problems in` volved by the use of simple and cient mechanism, thereby eliminating `substantially all manual positioning and removing operations. At the same time the apparatus is designed for large ca creasing the output and ecreasmg the cost of roduction ofthe completed box art. o these and other ends, there ore,y the nature of which will be "readil undetstoog as the invention is hereinafter isclosed,sa`

acity .thereby in#y required in the for?l Y order that the pintle invention consists in the improved construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out'in the appended claims.

i 23. :these views showing one forni of box partwrhich may be operated upon by the present apparatus, being one embodimentof a general type of metallic box part which is adapted to behliingedly connected to a complemental member to complete a commodity-receiving boxwls will be seen in Fig. 22, the blank consists of the bottom (or top, depending upon which is to carry the pintle) a@ and walls :10' Vforming an annular 75 flange which is substantially imperforate. This` is a common form ot' blank readily produced by dies.

As shown in Fig. 23, one of the walls ai has been operated upon to produce ears y] and a match-scratching surface w, a pintle p being inserted beneath the ears y, thus producing a box part to which the complenient-al member can be hinged in the usual manner.

Before entering into a detail description ot' the particular embodiment of apparatus disclosed herein, a brief statement of theseqnt-,nce of operations is given.

The blanks are introduced into the general feeding mechanism b v a traveling convcyer on which tlnl blanks are placed with the open side of successive blanks` in the saine direction. the conveyor bringing the blanks sncl-cssively into contact with a stop member which is arranged to act` somewhat on the order of an escaprment to permit the blanks to more forward individually at proper timed intervals. This permits the supply of blanks to be collected-oli the conveyor, sncceeding blanks being in contact, the stop permitting the blanks to escape one at a time. The escaping blank is introduced into n carrier channel within which it is advanced by an advancing mechanism which positions the blank at a predetern'iined pointA in this channel. The channel with its blank is thcn .shifted later-allir to place the blank within the operating zone of a reciprocatingr advancing instrumentality which actato advance the blank in the channel a distance sntlicient. to carry it out ot' the path ot' the succeeding blank, after which the channel is returned to its initial position. carrying Vthe shifted blank with it, thus permitting the introduction of the succeeding blank into its initial position in the channel, the advancing instrumentality returning to its` initial position after the channel hasl carried the blank out of the operative path of movement of the advancing instrumentality. The succeeding blank is then introducedthus placing two blanks within the channel-matter which the channel again moves transversely to carry both positioned blanks within-the operating zone of the advancing instrunieutzd-it The latter then advances, carrying both la'nks forward, thus cariving the advance blank to a position opposite the form and mechanism for preparing the wall 15;.

of the blank for insertion of the pintle, the succeeding blank being advanced and placed in thewposition which has been vacated by thc first blank, thus again leaving the entrance to the channel open to receive the third blank. The channel is then returned to itsinitial or normal position, placing the blank onA the form, `after whichV the advanc-"' ing instrumcntalit again returns. The preparation of the lank takes place during the period when the third blank is being received in the channel and while the advancing instrumentality is returning, the movcmient'of the latter shiftingthe position of `,the blank on .the form in order to permit its ready removal when the channel is again shifted laterally, the third blank then being in position. After the channel has been shifted to remove. the blank from this form, the advancing instrumentality is operated to advance the three blanks which have been successively positioned in the channel, the first blank passing to a position opposite thel pint-lea p lying fornnthe .second blank op posite the b ank preparing form and the third blank advanced out ol the entrance to the channel. Therefore when the channel returns to its normal position, it will place the first blanknow prepared to receive the pintleon the pintle-applying form, thc second blank will be. positioned on thc blank preparing forni, and the entrance to the channel will be clear for the succ-ceding blank. ln this position of the carrier, the, second blank will be operated on to produce the pintle-rcceiving cars, etc., a pintlc will be applied to the first blank, and a fourth blank introduced into the entrance to the.

channel, thus placing a blank at nach of the fonrstations within the channel. The pintle application is completed. while the first blank is positioned on tho form, after which the channel is again moved transversely, removing the tirsl and second blanks from their respective forms. the remaining blanks being shifted as explained. and the advancing instrumentality brought into action to advance the several iosiiioned blanks, this movement carrying the completed blank out of the channel and positioning the second blank on the. pintlevapplying form, andthe third blank on the blank preparing form.

As will be seen, this provides a step-bystep advancing movement to a; blank suc-i cessively to each of the stations, each operaf tion being similar, the carrier having a cycle rwhich carries it laterally and then back these operations beingr spaced by periods mi,

dwell, while the advancing instrumentality reciprocptes in diret-tions parallel to the .lengtbof the channel. the l' taking piace duringA periods oidwell of the -carrier, the movements of carrier and instrumentality being noirconeurrent.

Throughout the travel of thc blank, it rerate operation.

mains in the carrier channel, and the successive o erations described are such (assuming t e proper introduction of a blank whenever the entrance to the channel is unobstructed) that each cycle of back and forth movements of the carrier completes a box part, the blank preparing and pintleapplying operations taking place concurrently, a new blank bein introduced for each completed Ipart disciarged from the a paratus. Henne the capacity of the ma.- c ine is practically controlled by the length of time required to apply time required to advance the blank from one station to the next. The latter time is comparatively small for the reason that the shifting movements of the channel and of the advancing `instrumentality can be made With more or less rapidity.

As will be understood, no manual manipulation is required, other than that which might. be necessary in keeping the conveyer supplied with blanks. If the present apparatus is so positioned that the blanks delivered by a blankforming apparatus bc discharged on to the conveyor, manual feeding can be eliminated.

For convenience in description, I indicate the several stations as A, B, C and D, station A being at the entrance to the channel, station C being the station at which the blank is prepared for pintle-applying, and station D the pintle-applying station. No work is performed at station B, this station being designed more particularly to provide the, supply for station C without complicating the general operation by attempting to introduce a blank and properly locate it on the die at. station C at one operation, this introduction and positioning being divided into two steps, the first step being the introduction and initial positioning of the blank, thereby requirin a minimum amount of time to complete the initial positioningaction-a time within the limits of that required at the working stations-leaving the delivery ofthe blank to station C as a sepa'- This particular arrangement locates four blanks in the channel while the Working stations are operating, but the presence of this number of blanks does not affect the general operation.

A description of the invention will more or less follow the successive station operations.

rcciprocations Referring more particularly to Figs. 4 to w10, 32 designates an element-shown in de- 'SW of the frame.

.tail in Fig. 8-monnted on a. table portion n Element 32 comprises a vertical plate member 33 to which is secured the plntle and the Ian elongated member 34, the latter carrying a strip-like member 34 which forms the are ot' any desired length; conveyer 36 is preferably designed to be constantly driven. As the channel formed between members 34 and 35 is adapted to receive the blanks and form the supply for the leneral operations, it will be understood that the length of this channel is preferably suilicient to permit the operator to maintain a sutiicient number of blanks therein to supply the machine.

Conveyer 36 is adapted to advance the blanks positioned in the channel into coperative relation with a` stop member 39 earried by member said stop member being pivotallj,` connected, -is at. 39l1 to guide 40 (Fig. 11), members 33 and 34 having slots 33" and 34h respectively to permit the angular extension 39h to project into the ath oi travel of the advancing blrnks( a. spring 39 serving to nirmally retain the tapered end of the member in position to intersect the blank travel path as shown, for instance, in Figs. 4 to 6. As shown in these views, member 39 normally contacts with the advance of the rear wall of the blank, tbe major portion of the blank which is being held being in advance of the stop member, the latter being spaced from the advance end of the active conwyer flight a distance to permit of the blank beingr positioned in this manner and yet remain on the conveyer. Obviously, the succeeding blanks will be held against advance movement so long as stop member 39 holds the. advance blank from movement. The blanks which are succes sively positioned on the conveyer will be advanced until cach contacts with the preceding blankthe positioned and held blanks remaining stationary while the conveyer continues its movement. When, however, member 39 is moved on its pivot to withdraw its ta ered end from the feeding channels, the b anks ositioned on the conveyor will advance in tile channel until stop member 39 is Vagain made active. The normal position of stop member 39 is such as to intersect the travel ath of the blanks and is intermittently wit drawn from its normal position for a suiiicient length of time to per mit the contacting walls of the blank being held and the succeeding blank to ass by the tapered end of the member, the atter then returning to normal position to .contact with the rear w ll of this succeeding blank. Withdrawal movement of member 39 is provided by the followin mechanism: y

4l designates sli e mounted in guide 40 t l"lgs 11 and 12, sa'd slide carrying a pawl 42, pivoted at 42 to permit of a limited oscillatoryv movement, safid pawl carrying a finger 43 at its advance end, said finger projecting laterally throu h a slot 33b formed in member 33. Slide 41 1s adapted to be recip- I'Dcated b v it b ll crank lever 44 (Fig. 1) 4connected to pz vl 42 tby a link 44, lever 44 ibeing adaptedtth be rocked bv suitable mechanism operated by drive shaft 31, as for instance agcrank arm 45 and a link 45'* con-- necting the crank arm and bell crank lever, movementsl ot the crank arm, through the connections described, causing slide 41 to be reciprocated in guide 40.

Stop member 39 carries an element 46 hav ing a downwardly projecting portion 46 adapted to cooperate with au upwardly tending projection 47 of an clement 47 car ried on paw] 42. Projecting portions 4G and 47 (which may be in reversed relation) are adapted to function more or les:l as cam members, these projections havingn contigurations approximately as shown 1n Figs. 4 to 7 and operating in the following manner:

The advance position of pawl 42 is shown in Figs. 4 and 5, at which time nger 43 is at the advance end of slot 33".' At the proper time, slide 41 is moved rearwardly through the connections indicated, to the position shown in Fig. 6. As link 44a is connected directly te the pawl, the latter ill be initially rocked to withdraw finger Pawl 42 completes its movement in this direction with the parts in this position, projections 47a and 46a passing free during this movement. At the beginning of the return move ment of the slide, pawn] 42 will be rocked in thecpposite direction, so that durin such return movement the outer face of projection 47 will contact with the inner face of projection 46, as shown for instance in Fi 7, the resultl being that projection 46 wil be moved outward during the time required for these contacting faces to pass by each other. Since projection 46 is practically carried by stop member 39, this outward movement will cause member 39' to be rocked on its pivot to provide withdrawal movement of the taered end of said member. As soon as projection 47 passes out of contact with projection 46, spring 39 will return member 39.to its normal position. This period of withdrawal `of member 39, though short, is suilicient to permit the contacting walls of the two blanks to pass by the end of the sto member, thus freemg the advance blank and placing the stop member in osition to stop the movement of the succee `ing blank.

Finger 43 is designed more particularly to positively advance the released blank, this ingel, which is adapted to project through slot 34 in member 3l 'during the. return travel of paivl l2` projecting into the blank in rear of the advance ivall of the released blank (Fig. T). so that as the paivl continues its advance inoveincnt to the position shown in Fig. l. it will advance the released blank to the position shown in said Fig. l, moving the blank to a position' where its advance face is in proximity to or contacts with a stationary projection 33" carried b v meinber 33., This advance movi-nient of the blank carries the latter into a channel formed in a blank carrier 48 shown inore particularly in detail in Fig. 9--projeetion 33" extending into the channel at this time-the blank corning to rest at this point, this resting point being indicated as station A.. i v' For purposes ol' explaining the Inievements of the blanks` through the several stations, four successivi,- blanks will be indicated respectivel;Y ai il, r. 7 and a inthe order of their introduction to station A.

I

As shown in Fig. 4, the normal position of Carrier 48 is with its members 48 and 48" in longitudinal alinement with members 3l and 35, thus bringing the channel of the carrier in longitudinal alinenient with the eonveyei channel heretofore described.y this being the position of the carrier when the blank isabeifig introduced. Although not essential.y it is VUT ,.494 prclfeiied that omni 4b and ineinbtis o and 35 have opposing endconfigurations more or less interengaged, as for instance is shown in Figs. 8 and 9, thus tending to prevent undesired movements ol' either of these parts and presenting a smooth wall elfectf ('ain 5U is arranged to shift carrier 48 from the position shown in Fig. -l to [hat .shown in Fig. 5 and return, the shifting4 movements being comparatively rapid and oshort duration, tliecarrier dwelling in each of these positions to permit operations on the blanks to take place therein. lVlien in the normal position of Figs. 4 and 7,` the blanks are. in position to be operated upon, this being the blank-working position of the Carrier. Shiftin oftlie carrier to the po sition shown in iig. is for the purpose of advancing the blanks contained within the carrier to the succeeding stations, this advancing operation being provided by a reciprocating advancing instrumentality indicated generally at 53 and shown more. par ticularly in detail in Fig. ith the movements of this instrumentality beingrat right angles to the direction ot' nioveinent of the carrier and parallel to the direction ot length of thi-` eai'ricr channel. li'istrunieiitality is lol cated at one side of the carrier. element 32j at the opposite side.

Advancingy instrumentality 5:5 includes two nieinbers'l and member 5l beingr .slidaiblir iiiounteil in member 55, said ineinbei's. hoivew-r`- being adapted to normallyY travel in unison, being operatively connectiA i lV a yildablc element .36 carried by ineinbor 55 and projecting intoineinber 5l. Yieldable eloinent 56 is designed as a safety element to permit relative movement of inrnihr-r 34 and under abnormal condiA tif we. the rlrnir-nt bein designed to cause ih( rave] in nni--on iindernoiiin'al conditions. Mrrnber 55. which may be considered as :i lille ini-inbl-r. is mounted on a suitable stationary guido 43 at thriop of the table.

lleripiof'alion of. the advancing instrunieiitalittv is provided by a pivoted lever 58, the movement:` of which are controlled by a cani 5D on driv(l `shaft 3l, lever 58 having its ol'iposite end connected to slide member 55 through adjustable connection (30 mounted on pin .55a of member 55 (Fig. l).

Meniber 5l is prelfrablyI provided with tour projections 54a, 54". 5l and 54", these projections extending on substantially the saine horizontal plane and being spaced apart in the dirbction of length of member :il a distance :substantiallyY equal to 4the length of the blank, the distance bein such` as to provide a comparatively loose t of a blank between adjacent projections during the operation of the apparatus. These pr0- jeetions extend into a slot 48e of member 48 when the carrier is in its` normahposition, the length of the projections being prefer ably such as not to extend into the channel of the carrier in this position, as shown more particularly in Figs. 4 and 7. When, however, carrier 48A is shifted from its, normal position, member 485 moves over these projections a distance suilicient to cause the latter to intersect the carrier channel, as shown in Fig. 5, in which member 55 is shown in its rear position.

It may be noted that when member 55 is in its rearpositi-on, projection 54 will practically oppose projection 33 of member 33, while projection 54c will oppose projection 33'i of said member 33, as shown in Fi s. 4 and 5.

hen, therefore, blank d was positioned at station A, it was .located in alinement with the space between projections 54l and 54". Hence, 'when the carrier is shifted to its opposite position, blank d, while remaining in the carrier channel, is shifted into this space. Consequently, when instrumentality 53 iS advanced by the action of cam 50, thereby advancing the projections 'of member 54 a distance equal to the distance between the center lines of adjacent projections, blank d will be advanced in the carrier channel to a position opposite the space between projections 33(L and 33d of member 33, as shown by blank r! in Fig. 5. Instrumentality 53 dwells in this position, and during this period of dwell carrier 48 is returned to its normal position, thus carrying the shifted blank d into the space between projections 33c and 33d, this position of the blank representing station B.

After the carrier has thus returned, instrumentality 53 returns to its rear position, the movement of the carrier having taken the blankswhich may be in the carrier channel out of the path of travel of the projections of member 54.

This cycle of operations of the carrier has resulted in transferring blank d from station A to station B, leaving station A empty to receive the succeeding blank, indicated at c, which is introduced to this station while the carrier is in this position in the same manner as heretofore explained in res ect to blank d.

hc succeeding shifting mo ement of carrier 48 from its normal position locates the shifted blank d between projections 54 and 54 and at the same time positions blank c between projections 54a and 54". The advance movement of instrumentality 53 ,then

'advances both blanks, positioning blank c opposite station B and blank d opposite the blank preparing station C into which blank (l passes when carrier 48 returns to its` normal position, blank passing to station B, station A being empty to receive the succeeding blank, the general cycle being completed by the return of instrumentality 53 to its rear position. i

The blank preparing or manipulating mechanism by means of which vears y and match-scratching surface w are produced, is shown more particularly in Figs. 1, 13, and 14, in which 61 indicates a form which functions as a die member and is removably secured to a bracket 62 suitably supported on table 30". Form 61 has its front portion of a general peripheral configuration a proximating that of the interior of the wa 1s of the blank, the vertical length of this portion of the form being somewhat less than the distance between the topV and bottom Walls of the blank. The top of the form is provided with a pair of projections 61? (Fig. 5) and a more or less serrated portion 61", projections 61 providing the die configuration for the formation of ears y, portion 61 being a die configuration electfive in producing the match-scratching surace.

Form 6l is positioned at a point Where the blank is free to advance under the ac 'tion of instrumentality 53 to a position opposite this form, this taking place, as heretofore explained, While carrier 48 is out of its normal position. However, the return movement of the carrier to its normal position carries this blankon to form 61, the latter acting as an anvil of a die press structure. Since the top surface of the form carries projections, it is necessary that the blank be raised in order that its upper Wall may clear projections 61 while the blank is being located on the form. This raising movement of the blank is provided by mechanism now to be described and shown" more particularly in Figs. 13, 14 and 16.

Pivotally supported on the carrier is aA member '63 (Fig. 16) having itsfadvance end U-shaped and slotted to removably receive a pair of headed pins 63, these pins extending upwardly through member 48c of the carrier into the carrier channel (Figs. 13 and 14). The opposite end'of member 63 is provided with a roller 63" which is located in the slot of a cam member 64 car-- ried by slide member 55 (Fig. 10), the slot of cam member 64 having its opposite ends-64-lowered with respect to the intermediate portion 64" of the slot. When roller 63" is located at either end 648L of the cam slot, member 63 will be so positioned as to project pins 63 intr the carrier channel a distance sufiicient-,eb raise the upper Wallet the blank above the top of projections 61a; when roller t3" is in the intermediate portion 64" of tle slot, the pins will be withdrawn from thel channel permitting the blank to`be seated on the form or on carrier member 48 at thev bottom of .the channel.

Cam plate 64, being positively connected to instrumentality 53, reciprocates with the latter. On the other hand, member 63, supisb over projections 61?, permitting ported by carrier 48 is held against movement longitudinally of the carrier being movable with the latter during its back and forth movements. Hence, the movements of cam plate 64 will actuate member 63 to provide the pin projection and retraction at predetermined times. For instance, with instrumentality 53 in its rear position, pins 63 will project into the channel, roller 63 being in the advance end 64'* of the cam slot (Fig. 1), the this position being raised. As instrumentality 53 advances, it carries the blank from this position, advancin the succeeding blank toward this position. During this movement. roller 63b asses into the inter mediate portion 64; o' the slot andretracts pins 63, the result being that the advance blank drops on to the bottom of the carrier channel and advances on said bottom, while the suceeeding'blank is simply moved along on this bottom `to this position. As instrumentality 5B approaches the end of its advance movement, roller 63b passes into the rear end 614- oi the slot, causing pins 63* to be projected into the slot, and since the advancing rear blank is then in position over both pins, the blank is readily raised and its advance movement com leted while in raised position. Carrier 48 is then returned to normal positionwinstrumentality 53 remaining at rest in its advance position during this return movement--after which instrumentality 53 moves rearward, again` withdrawingpins 63 from the carrier chan nel through the action of intermediate portion 64" of the slot, the pins remaining withdrawn until instrumentality 53 approaches its rear position thus again projecting the pins into the channel.

`Since member 63 is shiftable with the carrier, roller 63 is of length sufficient to be operative in the cani slot in either position.

The die manipulation on thc blank is provided while the pins are retracted,-retracm tion` of the pins after the carrier has moved inward to locate` the upper wall of the blank the blank to lower and rest upon-these projections. While in this position, the die press operation brings the complcmental die structure into operation to produce the desired configuration, this mechanism being as follows:

65 designates the vertical reciprocating head of a die press, the head being operated' from drive shaft 31. this head carrying a die removably secured to a block 65". This die is shown in detail in Fig. 15, comprising a supporting member 66 havin a recess 66 to receive the die, the latter being preferably sectional in formv and vcomprising the main die member 6T having a recess 67a to receive die element 68, and an additional recess 67b to receive die element 69. The main die member is provided with the groove con tiene blank in the carrier in' the blank, it

which are complementary to figur-ations 67@ of die 61 in the formation projections 61 of ears y.

Die element 68 carries a air of projections 68 which substantially aline with grooves 67, projections 68, however, being located between said grooves. Projections 68'hi are adapted to cooperate with projections 61 in providing the necessary slitted condition of the blank to roiide for the open ends of ears y. In ad ltion, these projections 68"L are operative to depress the wall of the blank at the' entrance to each ear, projections 61a and 68, in operationpro ducing a configuration of the top `vail of the box substantially such as that indicated in Figs. 17 and 18, thus producing an entrance to each ear of a suiiicient size for the purpose without, however, requiring extensive ear projection, this arrangement being provided to facilitate the insertion of the pintle as presently described.

Die element 68 has a face compleinental to face 6lh of the anvil or form die to produce the match-scratching surface on the wall of the blank. Obviously, where it is not desired to provide the match-scratching Surface, the dic faces for producing this surface may be omitted, this surface being more or less of a convenience and not essential in the pintle-applying operation.

W'hen, therefore, the blank is located on projections 61, as heretofore pointed out, the movements of head 65 bring the several operating faces of the die carried by thisflOO movable head into contact with the wall and force the blank downwardly in producing the blank configuration, the movable die then being withdrawn as is usual in die press constructions. The time required to produce this configuration is short and provides cour plete die operation within the time during which roller 63b in traveling in the intermediate portion 64" of the cam slot. pins 63 therefore being out of the path of the blank while the latter is bein 'moved downward under the die action. ince the die action places projection 61a in the indentations of is essential thatthe blank be raised from this position before carrier movement-to withdraw the blank again takes place, and this raising of the blank for this purpose is provided b v the change in position of roller 63" as yinstrumentality 53 ap preaches its rear position.

As a result of these operations at station C. the completion of the cycle of mbvement of instrumentality 53 leaves the dieirodnced structure of the blank above the plane of projections 61", freeing 'any restraint against withdrawal movement` so that when the carrier again moves away from its normal position, this blank is free to move off of form 61 and into the space between projections 54 and old, thereby po- 130 the blank from -I figuration, as shown in these views.

sitioning the blank at a point where the succeeding advance of instrumentality 5B will carry this blank to a position opposite station D, the remaining blanks being correspondingly advanced, as heretofore described.

Upon the succeeding return movement of the carrier, the blank positioned opposite stationD is moved into said station and on to supporting form 70 of the pintle-a plyv ing mechanism, the succeeding blanks eing positioned in stations C and B respectively.

As shown more particularly in Figs. 17 to Q0, die 70, on its upper face, is provided with a. recess 70al of suitable length, this recess being located below the car configuration roduced on the blank in station (l. 71 in icates a slidable member suitably supported on form 70 and having an arm 71a extending through the form, member 71 having a hook end 71h, said member. 71 being normally located at one extreme of its movement (Figs. 17 and 18) in which position end 71b is located beyond the ear con- The operation of member 71 will be presently described, but `it may be noted that this member acts to shift the pintle 'to complete the pintle-inserting movement, and may also serve as a stop to limit the advance movement of the pintle Wire, although this is not essential. r

The general cycle of pintle positioning operations is as follows: After the blank has been positioned, a wire feeding mechanism made active to introduce the advance end of the wire through the opening beneath the rear ear of the blank (Fig. 17) g the pintle may be preformedr and introduced as a unit, but it is preferred to practically provide the pintle-length during the operation by cutting the pintle from a length of wire, which may, for instance, be supplied from a roll, and this particular type of wire supply is disclosed in the drawings. After the advance end of the wire is introduced, a vertically reciprocating member is brought into operation to cut the Wire at the proper point and move the cut end of the pintle downward into a position in alinement with the opening of the advance ear of the blank (Fig. 1S), and while in this position, member 71 is moved out of its normal position, the hook end 71" contacting with the previously Ainserted' end of the pintle and, pushing the `pintle ahead during the hook advancing movement. positions the advance end ofthe pintle beneath the advance ear l (Fig 19), thus inserting the pintle With the pintle ends extending beneath the ears and the intermediate portion exposed. As will be understood, the operation provides for inserting one end of the pintle a distance greater than that required in the final pintle position, positioning the unnserted end of the pintle opposite the entrance to the other ear, and then shftin the pintle in the opposite direction, this being the general idea disclosed in the patent to George heretofore referred to. The mechanisms for producing this cycle of operations will new be described: The pintle forming wire, indicated at 1' 1s supp troduced, between' a pair of feed rolls 72 and 72 nuiuntcd on a bracket 30" of the frame, roll 72 having a gear connection with an advancing mechanism, roll 72 being an idler adjustably mounted in bracket 30".

The advancing mechanism for the wire comprises :i shaft 73 carrying gear l forming the drive for roll 7 2, said shaft also having a ratchet 73" (Figs. 1,2 and 3). Loosely mounted on shaft 73 is a bell crank leverv 74 having one of its arms provided with a pawl 74 which cooperates with ratchet 73". The opposite arm of lever 74 carries a crank pin-74fh extending into un elongated slot 75a of a link 75 pivotally connected to a link 75l' pivotcd to one end of an arm 76, the opposite end of which is pivotully mounted at- 76. Arm 76 carries a roll 77'd which coioperates with a cam 77 mounted on drive `shaft 31.

Under normal operations, roll 72 will be intermittently rotated to advance the wire through the action of the link connections which, moving vertically, will permit crank pin 74h to move downward with link 75, permitting pawl 7 4'* to ratchet over the teeth of ratchet 73", the return movement of link 75 drawing pin 74h upwardly and thus causing ratchet 73b to he advanced through the action of pawl 74, the parts being so arranged that the advance movement of the ratchet will feed the amount of wire needed for the pintle. f

In order that no difficulty will be had through feed of wire in case no blank is being positioned to receive the pintle, I preferably employ a safety device which acts to prevent lever 74 from moving during the downward travel of link 75, link 75 eing movable downwardly while pin 74 remains stationary, slot 7 5 permitting link 75 to move while pin 74:b remains stationary, return movement of linlr 75 obviously having no effeet in advancing ratchet 73". This control is provided through the operations of an arm 78 having one end connected with 1ever74, and havin its opposite end formed with a hook 78 at apt-,ed to be engaged by the hookshaped end 79* of a ivoted lever 79, the opposite end of which` 1s connected to a link 79b whichl connects the lever with an arm 80. carried by a shaft 80said shaft carrying a finger 80" located in the` path of travel of a blank advancing from a position opposite icd from u lsuitable source, being in- I ias station C to that opposite :station D this mechanism being more particularly in Fig. 1.' Arm' 78 extends throu h a bracket arm 78" (Fig. 3) a spring 78 ein mounted on arm 78 beneath the bracket an tending t0 move ,arm 78 downward said sp1-ing thereby forming an element adapted to retain crank pin 74" at the bottom of slot 7 5L during movements of link 75. The parts are so arranged that upon completion of the advance of ratchet gaged by the hook-shaped end 79 as shown 1ny Fig. 1, finger 801 extending downward at this time. Should the succeeding operation of instrumentality 53 -fail to advance a blank into contact with finger 80", the lat,- ter will not be moved and hence the e a ement of the hook-shaped ends 78 an 9 will not be disturbed, the succeedin movement of link 75 thus having n0 e ect on roll 72. When, however, instrumentality 53 properly advances a blank from station C, the advance end of the blank contacts with finger 80" and moves shaft 8O which, through' connections 80 and 79", rocks lever 79 and moves end 79 out of engagement with end 78", leaving arm 78 free to move downward and thus permit pin 74b to follow the downward movement of link 75.

Wire r is passed throughl suitable straightening rolls 81 and between rolls 82 into a guide 83 which extends over the top of form 70. This guide is shown more articularly in Fig. 17 as in the form of a ho der 83`and a guiding member 83b through which the advance end of the wire is delivered, member 83" having its passageway of a size to permit the free movement of the wire therethroughand at the same time prevent mate rial swaying or other movements of the projected portion of the wire. f

As will be seen, the wire advancing means is preferably arranged at an angle to the horizontal, the angle bein such that the advancing wire will enter t e openin to the rear ear of the blank," as shown in Fig. 17, a guide 83c being arranged to correct any slight inaccuracy of movement of the advance end of thel wire and directing such advance end into this opening, itbeing understood that during ment member 71 is at or practically ap- ,Fi and 18, the wire feed movement being( provided by tne upward movement of link 75. This places the wire in substantially the position shown in Fig, 17 in which the rear end of the pintle (the advance end of the wire) has been inserted into the interior of the blank beyond the position which this end occupies when the pintle has been completely inserted, while the remainder of the pintle is ,still connected tothe `wire. The succeeding operation cuts. the

own

oac ing its normal position Shown 1n 73", hook 78EL will be enthis advance movev wire and locates it in the position shown in Fig. 18, this being provided by the followmechanism: ounted on block of head 65 is a member 84 shown moreparticularly in Fig. 21, this member having a recess 84 at one side, said recess being adapted' to receive a cutting member 85, the lower edge of which practically extends in the plane of the lower end of member 84. The lower end of members 84 and 85 are slotted, as at 84 and85 respectively, to form a guide for the wire, the bottom of slot 85a forming a cutting edge coperating with the exposed end of member 83b to sever. the wire at the desired point. Member 84 is also provided with a vertically extending opening 84 leading to an opemng 65" in block 65, said openings being adapted to receive a lunger 86'which normall `projects below t e bottomlane of mem er 84, as shown in Fig. 17. ook 65*L carries a cap member 87 in substantial alinement with opening 65", plun er 86 also extending through cap 87, sai plunger having a flange 86a bottom of the cap is mounted a spring 86". After the advance end of thewire (the rear end of the pintle) has been inserted, downward movement of head 65' carries members 84 and 85 downwardly. Plunger 86 first contacts with the wire and moves inwardly, thereby compressing spring86b, the wire passing into slots 85w and 84b as the head continues its travel. When the bottom of slot 85a contacts with the wire, the continued movement of the head provides a shearing action on the wire, thus relieving plunger 86 from restraint and permitting spring86h to expand and cause plunger 86 to drive the severed end of the pintle downwardly into position opposite the entrance to the advance ear, as shown in Fig. 18,slots 84h and 85a serving to guide this endof the between which and theY pintle during its downward movement `un der the action of the plunger, the plunger holding the pintle in proper position opposite the entrance yto the ear.

Whileain this position, member 71 Yis made active to cause thevhook end 71hv to contact with the rear end of the intle and ush the pntle forward. Since tlie advance end of the pintle is practically at the entrance to the advance ear, such pushing -or advancin movement of member 71 Will cause this a v ance end of the pintle to entr the ear, the rear end of the pintle at the same time being advanced until it is located under the rear ear, placing the parts in ,fthe position shown in Fig. 19 and completing the pintle-applying operation, producing the structure shown in Fig. 23.

. Upon the next movement of the carrier from its normal position, blanlnwill be moved olf of form .70 intothe the completed s ace in advance of projection 54", so that the succeeding advance movement of instrumentalit 53 will .carry this completed blank practica ly out of the carrier channel, depending o'n the length of the channel beyond station D. In the forni shown in the drawin rs, the advance movement of instrumentality 53 will advance the completed box toa position where it may fall out of the chunnel and be collected in suitable manner. l

The movements of members 7l are provided by a cam 71 coperating with a lever 71d connected to member 71 by link 71.

As heretofore pointed out, the blank during its advance throu h the various stations, is retained in the c annel of carrier 48. Since, however, the positions of the blanks in stations C and D are suoli that the supporting forms extend into the blank in either station, carrier 48 has its member 48"`pro v-ided with openin s 48' and 48g, these openings being divide by a art 48h which, as shown in Fig. 4, is locate to move between dies 61 and 70. Like in stations A and B, member 48" is arranged to shiftlhe blanks from stations C and l), a suitable number of projections 48 beingr provided on opposite sides of each ot' openings 48 and 48S to provide the necessary structure in i'ear of the blank to cause the blank to niove with the carrier, projections 48 extending into recesses 61c of fornrl and 701 of form 70 as shown in Fig. 17, so that while provision is made for the entrance of these forms into the blanks, the latter are still retained within the channel of the carrier 48.

Since thc moving elements above the blank in each of stations C and D are carried by block 65, it will be readily seen that the operations are concurrent in said stations.

, Since the apparatus i: designed to introduce a. blank each time the carrier returns to its normal position, thus locating a blank at each of stations A; B, C and D, the introduced blanks advancing step by step through' these stations, it will be readily understood thatthe apparatus requires but little, if any, manual mani iulation of the blanks; any blank manipu ation would be the introduction of the blank to the conveyor structure, the succeedin operations being automatic.

Owing to t e fact, that the various nianipulations are distributed through various stations and the amount of manipulation on a blank at a single station is comparatively small and of short duration, it will be obvious that the apparatus may be operated at comparatively high speed with a resultant large capacity and comparatively low cost of production of the completed box part.

Other advantages will be apparent. For instance, the 'various operating parts are of a type which involve no intricate mechanical movements, etc., the construction andgoperation of the several elements being' simple and therefore not liable to be readily damfwhich have been described-for the purpose of taking care of diiculties which might possibly occur through defective blanks or accidental wrong positioning of a blank. Should there be any failure in feeding of blanks to station D, either by accident or when the supply is exhausted, or at the beginning ot' apparatus operation (at which time the various stations are empty and no blank reaches station D until it has passed through the other stations) no feed of wire can take place; since o eration of the remaining parts can provi e no material daniagin conditions, 1t will be readily understoo that the apparatus will be operated efficiently and at a minimum cost, especial! since the positioning of blanks is had with substantial accuracy. g

Obviously, by the use of changed forms, dies, etc., boxes of various sizes and shapes can be mani ulated` and it is to be understood that a justability of parts, change of forms and dies, change in size of arts, etc., are all contemplated to meet individual conditions of use.

While I have herein shown and described a preferred arrangement and combination of parts, it will be readily understood that changes and modificationstherein may be required or desired to meet the various exigencives of this or other uses, and I desire to be understood as reserving the right to make any and all such changes and modifications as may be required or desired in so far as the same may fall within the spirit and scope ofthe invention as expressed in the acdcompanying claims when broadly construe I claim as new, is:
